Monday, Tuesday, and Wednesday were rest days as a result of back pain, massages for back pain, and panicked biochemistry studying. Back's feeling better and test is this afternoon, so I'm hoping to get in some work tonight. After doing some research, I'm hoping to make some form tweaks (i.e. maintaining a better lumbar curve) to my back squat which should help prevent the pain that keeps cropping up.

Update - did modified SS, complete with backoff in weight for the back squat and form tweak:

Back Squat 3x5 (132.5)
Bench Press 3x5 (90; 5-5-4)
3 sets unbroken kipping pullups (7-4-5)

Pretty psyched about the new pullup PR - that 7th one was a little ugly, but I'm so close to my 8 consecutive pullup goal for the end of July!
